short
that is used to store "out" and "inout" parameters in IDL operations.
If an IDL operation signature has an IDL short as an "out"
or "inout" parameter, the programmer must pass an instance of
ShortHolder as the corresponding
parameter in the method invocation; for "inout" parameters, the programmer
must also fill the "in" value to be sent to the server.
Before the method invocation returns, the ORB will fill in the
value corresponding to the "out" value returned from the server.

If myShortHolder is an instance of ShortHolder,
the value stored in its value field can be accessed with
myShortHolder.value.
